I want to upgrade the hard drive to at least 500GB. I know that I need an SATA drive, but, as I recently discovered, there are three different revisions. I presume, but I'm not sure, that the MacBook I want will have revision 1.0.

So, I have a few questions.

1) Is my presumption correct? Does the MacBook I want (Model Identifier MacBook2,1, according to Wikipedia) have SATA revision 1.0?

2) If I do wind up with revision 1.0, can I use a drive of a higher revision?

3) If I can use a higher revision, will I get the advantages of it?

4) If I can use the higher revision but can't get the advantages of it, can I modify the MacBook so that I CAN get the advantages?

5) Is there one good online resource or book that discusses all this? I think I understand the actual mechanical aspects of drive replacement. I'm just curious about compatibility issues and the reasons for them._________________1.42 GHz PowerPC G4/1GB RAM/250GB HD
